Buggy code:
public class BundleStartTracker implements Service < BundleStartTracker > { private static final Logger log = Logger . getLogger ( "org.jboss.as.osgi" ) ; public static final ServiceName SERVICE_NAME = FRAMEWORK_BASE_NAME . append ( "starttracker" ) ; private final InjectedValue < PackageAdmin > injectedPackageAdmin = new InjectedValue < PackageAdmin > ( ) ; private final Map < ServiceName , BundleStartTracker .

Fix:
bundle . start ( ( ( Bundle . START_TRANSIENT ) | ( Bundle . START_ACTIVATION_POLICY ) ) ) ;
